"The structure of such a space differs absolutely radically in one respect from that of a Euclidean space ... On physical grounds, this gave rise to the conviction that the metrical field was at the same time the gravitational field.", from "The Problem of Space, Ether, and the Field in Physics" ( "Das Raum-, Äether- und Feld-Problem der Physik." ), by Albert Einstein, 1934

"Was There a Beginning?", by Leonard Susskind, Stanford Institute for Theoretical Physics and Department of Physics, Stanford University, April 24, 2012

"Cosmology from quantum potential", by Ahmed Farag Ali of the Center for Theoretical Physics, Giza, Egypt and Saurya Das of the Department of Physics and Astronomy, University of Lethbridge, Canada, 29 December 2014, where by employing a quantum corrected Raychaudhuri equation ( QRE ) and deriving the 2nd order Friedmann equations from the QRE, these authors arrived at: firstly, a confirmed cosmological constant of its originally observed value thus giving confirmation credence; and, secondly from a derived quantum correction term, that the big - bang singularity is no more and therefore this quantum paper "... predicts an infinite age of our universe."
